Hi all I live in the Oregon and am trying to clean up some land to turn in to a pasture for Alpacas and due to the amount of rain we have been having latly I am unalbe to use a tractor to helop clear the brush. So I am trying to clear as much as possible by hand. I have found out that I have PI mixed with my black berrys all over my yard. My queston is does repeat exposure lessen the effects of PI or does it just cause a more server reaction with each exposuer. I am trying to not use chemicals due to teh fact that I have a year round creek on my property and I do not want it to get contiminated. Any help would be greatly appricated. |
